If all the rings are similar and the order in which they were worn isn't counted then there are 4C3 ways the rings can be worn or 4 ways. This is true if there is no choice in picking the four fingers from 5 of each hand. If it is to be considered then there are 5C4*4C3 ways to wear the ring ie., 5*4 = 20 ways.
